In 1861, Henry Dircks, a civil engineer, of London, published a work entitled "Perpetuum Mobile; or, Search for Self-Motive Power, During the Seventeenth, Eighteenth and Nineteenth Centuries." The book contains 599 pages, and was followed in 1870, by a second series by the same author entitled "Perpetuum Mobile, or a History of the Search for Self-Motive Power from the Thirteenth, to the Nineteenth Century." In these two books there is amassed a wonderful amount of material showing on the part of the author diligence, great patience and wide and thorough search.The author of these works was not enamoured of his subject, and his books clearly show that he was not writing them because of any interest he had in the subject of Perpetual Motion. On the contrary, they appear to have been written because of a deep detestation entertained by the author for the subject of Perpetual Motion, and a contemptuous pity for any one seriously interested in the subject. Mr. Dircks's works may be said to be the works of a scold. His sentiments were deep, and his impulses strong, which accounts for the vast amount of labor he did in the preparation of his books. Those books are now out of print, and it is believed by the author of this book that they may well remain so. They contain much material that no one would be justified in wading through. The most complicated mechanisms devised by enthusiastic dreamers are shown in the same detail with which the inventors described them in presenting them to the public, or to the patent offices. Little is to be gained by this. So complicated are many of the devices that only technically trained engineers could read them understandingly, and few technically trained engineers are now greatly interested in self-motive power devices. We believe that every useful or interesting purpose is served if enough devices are collected, classified and presented to show the various principles relied upon by the inventors; with an explanation of why they failed—i. e., wherein the principles relied upon are wrong, and while possibly not out of harmony with any mechanical principles then known, are entirely out of harmony with principles since discovered and now well known. In the preparation of this volume a vast amount of the information furnished by the two works of Mr. Dircks has been rearranged, reclassified, and used.Everyone who has to any extent, by environment, associated with the mass of people who are not technically educated, knows that the persons who are still interested in the subject of Perpetual Motion, and who still seek its attainment, are not technically trained engineers or mathematicians, but for the greater part untrained people of naturally strong mechanical sense, and of natural mechanical and mathematical adaptation.This book is written for the perusal of that large class of people. It is not designed as an argument either for or against the possibility of the attainment of Perpetual Motion. The author is content to classify and present—clearly, it is hoped—the leading endeavors that have been known in that field of effort, and to explain their failure. It is believed by the author that the perusal of the present volume by anyone whose mind has been attracted by the subject of Perpetual Motion will result in an enlightenment, and, it is also believed, will have a tendency to direct his mind from a struggle with theories long ago exploded, and may result in directing his efforts to things practical, and not without hope of attainment.This work is offered only to minds mechanically or mathematically inclined. It is not even hoped that it will interest people who prefer fiction to fact, nor people who read simply for idle entertainment. ABOUT AUTHOR: The author has no apology to offer for the production of this book. He has spent his life in environments that have brought him into constant contact with mechanics, artisans and laborers as well as professional men, engineers, chemists and technical experts of various types. He knows a great many men—young men, for the most part—are constantly working on the old, old problem of Perpetual Motion; that much money, and much time are being spent in search of a solution for that problem which all scientific and technical men tell us is impossible of solution.It is believed by the author that a classification and presentation of selected groups of the devices produced in the past by which it was by the inventor believed, self-motive power had been attained, will save much work in fields already thoroughly exploited.So far as the author knows no book on the subject has appeared since 1870. The various encyclopedias published contain articles on the subject, but they are necessarily brief, and not satisfying to young men who have become interested in the subject.

One more point deserves notice. Butler often refers in “Life and Habit” to Darwin’s “Variations of Animals and Plants under Domestication.” When he does so it is always under the name “Plants and Animals.” More often still he refers to Darwin’s “Origin of Species by means Natural Selection,” terming it at one time “Origin of Species” and at another “Natural Selection,” sometimes, as on p. 278, using both names within a few lines of each other. Butler was as a rule scrupulously careful about quotations, and I can offer no explanation of this curious confusion of titles.? Since Samuel Butler published “Life and Habit” thirty-three [vii] years have elapsed—years fruitful in change and discovery, during which many of the mighty have been put down from their seat and many of the humble have been exalted. I do not know that Butler can truthfully be called humble, indeed, I think he had very few misgivings as to his ultimate triumph, but he has certainly been exalted with a rapidity that he himself can scarcely have foreseen. During his lifetime he was a literary pariah, the victim of an orga-nized conspiracy of silence. He is now, I think it may be said without exaggeration, universally accepted as one of the most remarkable English writers of the latter part of the nineteenth century. ??I will not weary my readers by quoting the numerous tributes paid by distinguished contemporary writers to Butler’s originality and force of mind, but I cannot refrain from illustrating the changed attitude of the sci-entific world to Butler and his theories by a reference to “Darwin and Modern Science,” the collection of essays published in 1909 by the University of Cambridge, in commemoration of the Darwin centenary. ??In that work Professor Bateson, while referring repeatedly to Butler’s biological works, speaks of him as “the most brilliant and by far the most interesting of Darwin’s opponents, whose works are at length emerging from oblivion.” ??R. A. STREATFEILD.?November, 1910.

Mér? László korábbi nagy siker? k?nyvei komoly szellemi kalandot jelent?, gondolkodásra késztet?, ugyanakkor szórakoztató olvasmánynak bizonyultak. A Mindenki másképp egyforma 1999-ben elnyerte az ??v tudományos k?nyve Németországban” díjak egyikét. Mér? László új k?nyve a szerz? r?videbb, de nem kevésbé elmélyült, elgondolkodtató és szórakoztató írásait tartalmazza. Ezek t?bbsége a Magyar Narancs Egotrip rovatában jelent meg, a k?nyv címe azonos a szerz? ottani sorozatcímével. Ebben a k?nyvben a szerz? a legt?bb írást alaposan átdolgozta. A lényeg nemigen változott, de a szigorú újságcikk-m?faj szorításából kiszabadulva némelyik írás hosszabb, némelyik r?videbb lett – ahogy a téma kívánta. ?s hogy mi ez a talányos cím? A magyarázatot keresse a k?tetben! ?Eredeti szakmám matematikus, majd a m?szaki tudományokból kandidáltam, kés?bb pszichológiából lettem habilitált doktor, nemrég pedig a gazdaságpszichológia professzorává neveztek ki. Emellett k?zel húsz éve vezetek egy játékszoftver-fejleszt? céget, amelynek egyik alapítója vagyok. Tudományos szakcikkek mellett írtam néhány k?nyvet a szélesebb olvasók?z?nség számára is, ezek t?bb idegen nyelven is megjelentek. Az utóbbi években megszerettem a tárca m?faját is – ennek termését mutatja be ez a k?nyv.” Mér? László
